There were discussion about objective cards awhile back and now I made some myself and tried them out.

(The battle was fought using my hack rules. WIth standard rules, the word "round" below refers to the time it takes each player to complete a turn, starting with the first player.)

How to do it
You have a deck of objective cards. At the start of the game, you draw five cards from the deck and place them face up on the table, and place one Victory Point on each of them. 1x2 bricks work well as Victory Points.

When a player completes an objective, they receive all Victory Points on it, and the objective card is discarded.

If an objective becomes impossible for all players to complete, discard it. Eg. a Hero-reliant objective becomes impossible if all players lose their Heroes.

At the start of each following round, draw new objective cards if there are less than five on the table. Then place one Victory Point on each objective card. This means the longer it takes the players to complete an objective, the more points it will be worth.

A round limit for the game is probably a good idea. We played five rounds, that felt about right.

Looking good! Have you considered the objectives to be multi-staged? That is, they have multiple stages of completion, and for each stage completed you gain a victory point.
For example: you have to repair some sort of mining machine to start digging for resources. Suppose, only robots can operate that machine. So first you need to find and activate a robot (+1 victory point), then you sit him down in the mining machine (+1 victory point), and, finally, you get this machine to the mining area (+1 victory point). Once the machine starts mining, you gain all 3 victory points. You have to complete all three stages for victory points to transfer to you. So, if a robot pilot or his machine are destroyed, no victory points whatsoever.
Of course, this particular example involves you defending something over multiple turns, of which not all BrikWarriors approve, but you get the general idea.
